Do the side lengths 9,12,15 classify as a right,acute,obtuse triangle, or “no possible triangle”
HACTEHA [7]
Refer to c^2=a^2+b^2 (^2 means squared)
C is the hypotenuse and will be the longest measure
So 15^2= 9^2+12^2
225=225
If both sides are equal then the triangle is a right triangle, if the hypotenuse (or c) is lower or higher than you can determine whether it’s obtuse or acute
It would be a right triangle

Giuliana has 22 quarters and dollar coins worth a total of $10.75
nataly862011 [7]
Quarter is $0.25
Dollar is just $1
x is amount of quarters
y is amount of dollar coins
Two equations we know
0.25x+1y=10.75 and
x+y=22

solve both for y
0.25x+1y=10.75
y=10.75-0.25x

x+y=22
y=22-x

set them equal
22-x= (y) =10.75-0.25x
11.25=0.75x
x=15 quarters

then put x=15 into either equation and now solve for y

x+y=22
15+y=22
y=7 dollar coins

Blake rows his boat against a current 90 yards in 15 minutes. With a current, he rows 90 yards in 9 minutes. What is the rate at
Anna71 [15]

Answer:

90 yards in 15 minutes =6 yds/min

90 yards in 9 minutes =10 yds/min

x = current rate

r = rowing rate

r + x = 10

r - x = 6  Adding both equations

2 r = 16

rowing rate = 8 yds/min

x = 2 yds/min (current rate)
